Identify the device described as a curved metal frame that fits over the edge of a roof or windowsill.

• A. Hose roller
• B. Fog nozzle
• C. Standpipe
• D. Master stream appliance

Answer: (A)

The device described is a hose roller. It’s a curved metal frame that sits over the edge of a roof or windowsill to protect the hose and guide it as you pull it up or across the edge. The curve provides a smooth turning point, preventing the hose from snagging, kinking, or being damaged by the edge while you advance the line. The other options aren’t about protecting or guiding hose over edges: a fog nozzle is a spray nozzle, a standpipe is a vertical building pipe system, and a master stream appliance is a large-diameter nozzle for heavy flows.
